To all whomj t may concern.

Be it known that I, HAROLD G. DAVIS, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in AirHose Protectors; and I do declare the following to be a full, clear, and exact description of the in-y vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to a means adapted to protect the air hose at automobile service stations and garages. y

It is the universal custom today to have a supply of compressed air at all garages and filling stations for the convenience of the customers. The compressed air is piped to convenient locations near the curb o-r Yto any convenient place and a flexible hose is provided at the ends of the'l pipes. The hose is equipped with an automatic valve that opens when the hose is applied to the valve stem and closes when it is removed therefrom. When the user is through with the hose he ordinarily throws the same on Where it is in the way and presents an untidy appearance, both of which are highly objectionable.

lIn order to protect the hose from injury and prevent it from presenting an untidy appearance, efforts have been made to produce automatic reels which are enclosed in a suitable housing and which will permit the hose to be wound thereon when not in use. These automatic hose reels have not proven to be a `commercial success and have `not been extensively employed.

It is the object of this invention to produce a simple and efticientwarrangement for protecting an air hose which, aside from its simplicity, shall have a neat appearance and be adapted to remove the hose from the surface of the ground and fully protect the Asame when not in use.

My invention, briefly described, consists of a suitable casting which maybe embedded ina pavement or in the surface of the Aground and having an opening for the reception of a tube which extends into the r ground a distance substantially equal to onehalf the length of the hose. The air pipe projects through the wall of the casting and one end of the hose is connected to the end of the pipe. A cover is providedfor the casting. This cover has a hole therein through which the hose extends. A pulley and weight are applied to the hose within the tube and tend to pull it down thereinto.

In order better and more clearly to de- 'Scribe my invention, I shall have reference to the accompanying drawing which shows to designate the Jsame parts throughout the p 'several views.

Numeral 1 designates the surfaceofthe ground or the pavement where the air hose is located. At the proper pointfa circular vertical hole is sunk into the ground. This hole is approximately six inches in diameter and of a depth substantially yequal to onehalf of the length of the hose that is to be used in connection herewith, and maybe considered to be about ten feet in depth. Em-

bedded in the ground or the pavement with its upper edge substantially Hush with the surface, is a.-,astiron ring 2 which ispreferably circular and has a pocket 3 on one side thereof. The inner surface isl ralobeted along its upper edge, as indica-ted by numeral 4, toform a ledge upon which lthe cover 5 may rest. The coverv is circular and has a rectangular part 6 secured to one side thereof and is'of such size that it will fitzsnuglyin the top of the ring 2in the mannerV shown inFigs. 2 and 3. Two

lugs. 7 project downwardly lfrom the lower surface of the cover and each has an opening that aligns with a similar opening in be inserted througho these openings and the .side of the ring 2. A cotter pin may serve to hold the cover in place. Aftube 8 of galvanizedy sheet metal vis inserted-in the ring and extends downwardly to the bottom of the hole and forms a casing or lining therefor. The air pipe 9 which connects with the compressed air supply, extends through the wall of the pocket 3 and projects a s ort distance thereinto. The air hose 10 is connected at one end to the end of the pipe 9A and the other end extends throu h a hole 11 in the cover. The hose extends around a pulley 12 which is rovided with guides 13 arranged in the orm of a T. A weight 14 is secured to the lower end of the bottom guard. The action of the pulley 12 and weight 14 is such that it tends to maintain the parts in the relationship shown in Fig. 2. Surrounding the hole 11 are four lugs 15 which are provided with transverse openings 16 and 17. Rotatably mounted between each two adjacent lugs are pulleys 18. Pins 19 extend through holes 16 and through one -set of rollers 18 and pins 2O extend through holes 17 but are of such length that they reach only between the pins 19 and are held in place by them. The hose 10 projects through hole 11 in the manner shown in Fig. 2 and when its outer end is grasped and pulled the hose will rest upon one or more rollers 18, regardless of the position in which it is pulled. A ring 20 (Fig. 2) is clamped onto the hose and limits its entrance into the casing. The end of the hose is provided with the ordinary valve 21. The wei ht 14 should be as light as possible, but s ould be heavy enough to pull the hose into the casing, even if it is dropped full length on the ground. An electric conduit 22 passes through one side of ring 2 in the manner shown in Figs. 1 and 3 and serves as a means for introducing the electric wire 23. The cover has a hole about at its center and a pipe 24 threaded thereinto. To the top of this pipe a hollow drum or canteen-shaped sign 25 is rotatably connected. This sign is made of metal and has stenciled in its sides the words Free air. The upper cylindrical connecting portion 26 is made of metal and the corresponding lower portion 27 is made of wire screen2 so that the light from the lamp 2S may shlne down upon the ground and illuminatethe device. The sign has a bracket 29 which is perforated and rotatabl lpounted on pipe 24 between nuts 30 an 3 For the purpose of preventing the weight 14 and pul ey 12 from rotating and thereby twisting the hose, I have formed the weight with a notch 32 in its edge and have sey cured to the, inner surface of the casing 8 'an angle iron 33, one iange of which cooperates with the notch 32.

Although I have described my invention in connection with an air hose, itis evident that the same arrangement can be used for a water hose and a separate device may be installed to accommodate a water hose for filling radiators. This arrangement can be conveniently employed for protecting the sprinklin hose on lawns and in gardens and can, in act, be used wherever a flexible hose is employed.

From the above it will appear that I have produced a simple and eflicient device for protecting an air hose. This device has no springs and no moving parts, except the rollers 18 and pulley 12, and can be cheaply and quickly installed by merely digging a hole in the ground with a suitable earth auger and placing the device therein. Where the surface is concreted, as is usually the case, the concrete is brought up to the sides of the ring.

Having now described my invention, what I claim as new is:

An air hose protector comprising a ringlike member of metal having an outwardly projecting pocket in one side thereof, a rabbet along the upper inner edge of said ring and pocket, the wall portion of said pocket having an opening adapted to receive anair pipe, a cover adapted to fit said member and to rest in said rabbeted portion. a casing secured at its upper end to said ringlike member, diametricall opposed guides secured to the inside o said casing, a weight operatively related to said guides, said weight having a diameter substantially the same as the inner diameter of the casing and ringlike member and a pulley secured to the upper surface of said weight.

In testimony whereof I affix my signature.

HAROLD G. DAVIS.
